WILLIAM H. HEAVERIN, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO WILLIAM H. GALVERT, OF SAME PLACE.

oAR-CoUPLING.

SPECIFICATION forming part of Letters Patent No. 266,472, dated October 24, 1882.

l Application tiled July 31, 1882. (No model.)

To all whom it mag/'concern Y Be it known that LVWILLIAM Il. BEAVER- IN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Oar-Couplings, of which the following is a full, cleargand exact description, reference being had Yto the accompanying drawings,fortning part of this specilication, and in which- IO Figure l is a side elevation; Fig. 2, a front View; Fig. 3, an enlarged top view of two heads; Fig. 4, al1/enlarged vertical section; and Fig. 5 is an enlarged vertical section of one ot' the draw-heads, illustrating the manner I5 in which a common coupling link and pin can be used.

Myinvention relates toacar-conpling wherein a hook is employed on each drawhead to engage theother head; and my invention con- 2O sists in the peculiar construction of the drawheads, which are duplicates.

A A represent parts ot' two ear-bodies, and B B the draw-heads. Each draw-head has pivoted to it a hook, O, by means of bolts I) 25 in holes d, and they are constructed with open tops and hollow centers, E, which form a web, F, on the lower portieri of each draw-head, near the mouth, over which the hook of the opposite draw-head engages. (See Fig. 4.)

3o The webs F have concave inner faces, G, and the hooks are somewhat bowed in their shanks, so that there is no point ot' bearing between the pivot-pin ofeither of the hooks and its point of bearing on the other draw-head, and as the 35 lower end of the hook does not bear against the inner concave surface of the web F it will be seen that when one draw-head is depressed and the other not (as when one car only is loaded) the hook will not be disengaged from the other draw-head, but the point of bearing 4o will always be, under all such circumstances, atthe turn ot' the hook, as shown in Fig. 4, where it is the strongest, and no undue leverage or strain hy the point of bearingapproaching the end of the hook occurs. 45

The hooks may be raised when uncoupling or when either one'is not in use by any suitable means. I have shown them with leathers H on their forward ends, to which cords are attached that pass over pulleys secured to the 5o ends of the car.

' Common links and pins may be used by inserting block I in dovetail grooves J in the heads, the blocks having openings i and the heads openings t" to receive the pins.

The lower part of the mouth of the drawheads and the sides have the usual inclined faces, as shown, up the former of which the inclined forward end 0i the hook travels in coupling. 6o

I claiml. A draw-head formed with hollow center E, rearwardly-inclined cross-web F, having concave inner face, G, and transverse bolt-hole in the rear oi' the hollow center, as set forth.A 65

2. A draw-head formed with hollow center E, inclined cross-web F, having concave G, transverse bolt hole d, dovetail horizontal groove J, pinhole t,and dovetail block I, having pin-hole t', the whole being adapted for the 7o use of eitherV coupling pins or hooks, as set forth.' g
